Abstract :
The authors report the first electrodeposition of mercury zinc telluride (HgxZn1-xTe) thin films. Using a galvanic approach, the authors have deposited films of composition varying between x=0 to x=0.4 on indium tin oxide (ITO)/glass substrates. The films were found to be smooth, uniform and adherent with a small grain size (0.1-0.9 μm), polycrystalline structure. X-ray diffraction analysis of the films indicated a shift in the (111) peak with alloying in good agreement with a Vegard´s law behavior. The optical absorption edge was found to be a soft, direct band edge with optical absorption coefficients of the order 104 cm-1
